Creatine - 500 grams (1.10 lbs)

Creatine monohydrate, a precursor to creatine phosphate is
necessary to fuel muscle contractions. Creatine plays a vital role in
the creation of adenosine triphosphate (ATP), the primary compound which
converts food into energy. When high concentrations of creatine are
present, the body can quickly release ATP to sustain high-powered muscle
contraction. Used by athletes and body builders for years, creatine is
also useful (when combined with resistance exercises) to combat
age-related muscle wasting.
